Materials and methods. The records of causes of death of 34.914 persons aged 60 years and older were used as primary source of information. The initial cause of death was determined according to the ICD-10 rules. The rate of registration by reason of death was calculated as intensive value per 100 deaths in concrete age and sex group. Each cause was coded according to the ICD-10 rules (revision 20142016). The belonging to group was determined by first character (letter) in four-digit code that corresponded to the Class.<br />On the basis of analysis of structure of causes of death, the group A of causes that included five Classes of ICD-10, determined 81.4% of all deaths in population aged 60 years and older. Two Classes: Diseases of the circulatory system (Class IX) and Neoplasms (Class II) determine in all studied age groups more than a half of all deaths (from 55% to 71% of males and from 59% to 67% in females) and namely they determine mortality rate in older age groups. There are no gender differences in age characteristics of registration rate in these groups (p 0.05), however age dynamics differ. In case of diseases of circulatory system initial cause of death is increase rate of registration at increasing of age. In case of neoplasms at increasing of age decrease of registration rate as initial cause of death is established. At that, rate of decline is higher than rate of increase that determines certain decrease of structural significance of combined contribution of these two groups of causes at increasing of age. The Group B of causes, including three Classes of ICD-10 Respiratory diseases (Class X), Diseases of the digestive system (Class XI) and Diseases of the nervous system (Class VI), determined in overall 11.9% of all deaths in population aged 60 years and older.<br />The age dynamics of causes of death of population of older age groups exists for certain groups of causes and it should be considered in organizing medical care of population of older age groups.</p>older age groupscauses of deathICD-10planningstructure of causes of deathстаршие возрастные группыпричины смертиМеждународная классификация болезнейпланированиеструктура причин смерти1.Lisitsyn Yu.
